Résumé traduit
Translated abstract
In arable crop landscapes, featured by patch dynamics and field-wood relationships, field margins can be a unique ecological network allowing wooded species to break their isolation; therefore they are relevant for enhancing biodiversity. This work analyses the botanical composition of field margins and its agricultural and spatial factors. Data from 16 farm surveys and 127 botanical relevés were processed using correspondence and canonical analyses. Seven variables, mainly describing farm and field level, are significant according to the Montecarlo permutation test. We showed that in this patch, landscape farm territory is a relevant level of organisation for analysing arable crop landscapes and field-margin botanical composition.
